Space Projects Learning

Make a Spectroscope and explore the spectrum of different light sources. You’ll see all kinds of rainbow! This science activity for kids makes a great addition to a unit on light or weather. Light experiments are always fun, especially when they involve rainbow! In this science activity kids will make their own spectroscope- an instrument used to split light into different wavelengths, which we see as different colours of the rainbow how it works start by taking your spectroscope outside. Point the top slit up at the sky (not directly at the sun). look through the peephole. You will see a rainbow inside! A CD is a mirrored surface with spiral tracks or pits. These tracks are evenly spaced and diffract light (Separating the colours). because the cd’s surface is mirrored, the light is reflected to your eye.Make a spectroscope and explore the spectrum of different light sources.

his item:THE CURIOUS BRAIN MAGLEV Train - Engineering Ready Project - Mechanical Engineering Project kutuhal. fun with electromagnetism. contains required material and usage manual. perform 40 do it… StepsToDo (with device) Hydroelectric Power Generation DIY Kit Don’t live in Shanghai and can’t wait another 10 years to see a maglev in operation? Enlist a group of friends — or even your whole class — to make a working maglev model with an armload of items found in most hardware stores. This maglev model accurately reproduces the setup of magnets used in Shanghai’s maglev system and is made up of two parts: the train and the track. Much like a full-sized maglev system, the track and train need to be precisely matched to work: At every step in this project, look to see if lines are straight and magnets are evenly spaced. “Maglev trains in use today use computers to turn electromagnetic fields on and off in the right order, many times a second along the tracks. In this model, you can do the same thing without computers by adding and subtracting weights until your model hovers above the rails you’ll construct. Believe it or not, the air-gap between a real-life maglev and its tracks is 6 to 10 mm (1/2 in. to 3/8 in.). Your model may have just a small fraction of that gap and still be able to ‘levitate.’” Batteries Required ‎No Batteries Included ‎No Color ‎Multicolor Manufacturer recommended age ‎16 years and up Manufacturer ‎Junior Scientist
